While we aren't sure that there were 10,000 troops coming into Virginia on that night, I think its safe to say that there were: "thousands."

Obviously there were more than a hundred. In context, however, the statement implies overwhelming force and aggression. If all the site could say was "thousands," it raises the suspicion that it had no idea how many there really were. In short, thousands is a cop-out for research.
You shouldn't have expected that the folks doing the: "Cronology" site would have said that Lincoln: "demanded" troops from Virginia and the other states. After all, the group doing the "Cronology " site is in Albany, NY.

Never did contend that yankees were literate. Just that they were a bit more careful with their hyperbole.
